How to convert gallons to tablespoons
tablespoons = gallons × 256
Example: 2 gal × 256 = 512 tbsp.
Multiply the gallons by 256. The factor comes from two kitchen facts: a gallon holds 16 cups and every cup holds 16 tablespoons, so 16 × 16 = 256.
An eighth of a gallon, which is one pint, holds 32 tablespoons. A sixteenth of a gallon is a single cup of 16 tablespoons, and 3 gallons hold 768 tablespoons.
Nobody spoons out a whole gallon, so this conversion earns its keep in reverse. It matters when a label or recipe gives tablespoons per gallon and you are making a smaller batch.
US vs UK gallons and tablespoons
The tablespoon changes along with the gallon. Recipes from the UK and Canada use a metric tablespoon of 15 ml, Australian recipes use one of 20 ml, and the US tablespoon is 14.79 ml.
The answer shifts with each combination. A US gallon holds 252.4 metric tablespoons, an imperial gallon holds 307.4 US tablespoons, and the same imperial gallon holds 227.3 Australian ones. One spoon hardly differs from the next, but across a gallon the gap adds up to several spoonfuls.
| Unit | Size | Used in |
|---|---|---|
| US gallon | 3,785 ml | US |
| imperial gallon | 4,546 ml | UK |
| US tablespoon | 14.79 ml | US |
| metric tablespoon | 15 ml | UK, Canada, New Zealand |
| Australian tablespoon | 20 ml | Australia |
Scaling a per-gallon amount to a smaller batch
When a brine, drink mix or plant food label gives tablespoons per gallon, work out what share of a gallon you are making. A quart is a quarter of a gallon, a pint is an eighth, and a cup is a sixteenth.
Say a brine calls for 8 tablespoons of salt per gallon. For one quart, use a quarter of that, 2 tablespoons; for a pint, 1 tablespoon; and for one cup, 1 1/2 teaspoons. Level each spoon so the ratio holds as the batch shrinks, and note the per-quart amount on the recipe so the next small batch needs no math.
Gallons and tablespoons: questions
How many tablespoons are in half a gallon?
Half a gallon holds 128 tablespoons. That is the same as 8 cups, so a measuring cup is the sensible tool, and gallons to cups covers other sizes. Save the tablespoon for the small additions that go into the liquid.
How many tablespoons are in a quarter gallon?
A quarter gallon, better known as a quart, holds 64 tablespoons. If you know that a cup is 16 tablespoons, you can check it quickly: the quart has 4 cups, and 4 × 16 gives the same answer.
What is 1 tablespoon per gallon in a cup?
It is 0.1875 teaspoon per cup, just under 1/4 tsp. A cup is a sixteenth of a gallon, so it gets a sixteenth of the tablespoon. For strong ingredients, mix a full quart or gallon instead, where the amounts are easier to measure.
How many tablespoons are in a gallon and a half?
A gallon and a half holds 384 tablespoons. Put another way, that is 24 cups or 6 quarts, which are much easier to measure than a pile of spoonfuls. Keep the spoon for the seasonings that go into that volume.
